WP Cache Plugin Deletes itself

I downloaded W3Speedster and found that it checks if this plugin is active and recommends it be deactivated, and it then deletes this plugins’s config file.

    function w3_check_super_cache($path, $htaccess){
        if($this->w3_is_plugin_active('wp-super-cache/wp-cache.php')){
            return array("WP Super Cache needs to be deactive", "error");
        }else{
            @unlink($path."wp-content/wp-cache-config.php");

            $message = "";

            if(is_file($path."wp-content/wp-cache-config.php")){
                $message .= "<br>- be sure that you removed /wp-content/wp-cache-config.php";
            }

            if(preg_match("/supercache/", $htaccess)){
                $message .= "<br>- be sure that you removed the rules of super cache from the .htaccess";
            }

            return $message ? array("WP Super Cache cannot remove its own remnants so please follow the steps below".$message, "error") : "";
        }

        return "";
    }

I don’t know if the PRO version deletes the action plugins/wp-super-cache folder, but this one definitely deletes the config file, which is a bit much.

I’d recommend Jetpack Boost which does a similar job and does work well with this plugin. I work on Boost too, so I would suggest that, of course. ??

Thank you for looking into this Donncha, it is greatly appreciated.

It turns out that WP Engine, the WordPress hosting provider, has been deleting the Cache plugin as they have it on there Blacklist of plugins.

Here is an extract:

Caching Plugins

Caching plugins can conflict with our platform’s built-in caching structure. These plugins are known to cause direct conflicts and would ultimately impact your site’s ability to load if used:

• WP Super Cache
• WP File Cache
• W3 Total Cache

Many of the caching features these plugins offer we have built-in to our servers by default as part of your managed WordPress hosting experience. We have your back- don’t worry!

I am currently working on applying another WP cache fix for the website as the server side Cache services are not adequate in achieving good Google core metrics.

Ah, that makes sense. Glad you found out what caused it. Give Boost a go. The free version is very generous in what it does and may suit your needs.

I will try that plugin too, thanks again.
